The street argument is retarded. BJJ is so much overkill for the street that its ridiculous. Unless you're the idiot that picks a fight with the high school wrestling team, barring knife or gun play, the opponent shouldn't make it past double leg + ground and pound - Osiris

"Side note: I was told to use flippers in the pool with a kickboard for rehab. Does that seem about right?"

You sound like you may already know this but it probably depends on what your kick looks like.

A technically good freestyle kick starts in the hip and has very little knee bend. Beginners tend to have a lot of knee bend. (But flippers tend to straighten out peoples leg and get them to kick from the hip).

I'd second talking to your PT but have an idea of what kind of kick you have. (If your really keen, get someone to film you on a cellphone). I don't know what movement you're looking for but it may make a difference. There is a dramatic difference between the two movements.

So, I've got a first degree sprain, as per the MRI. The PA tells me to keep it on the low for at least six weeks. I hate the PA.

I've figured out that I can't really get around too well without a knee brace on. I've taken it off a few times to see what would happen and I basically felt like I was going to fall down. My PA (the bastard) told me that I could expect some degredation in ability through lack of use. He wasn't really kidding. It feels like jello to not have the brace on. I thought that much like what happens when you're a kid that I'd get a little hurt, rub some dirt on it, and be on my way shortly. It's only been a week since it happened, but except for the fact that there is limited pain, there is a considerable impact on mobility/stabilty.

In short, I'm a gimp and an easy target. I couldn't outrun a quadraplegic laying on the ground.
